Abstract:

Building on previous studies of the energy that can be harvested with a two degrees of
freedom oscillating buoys system, in this Master’s Thesis the analytical solutions for the mass
displacements of a two degrees of freedom system with viscous and Coulomb plus viscous
damping is found. These analytical solutions are compared with numerical results to prove
their validity.
The frequency response of the mean dissipation power for the previously commented dampers
is investigated, and it has also been set up a numerical simulation file which calculates the
mean dissipation power of a two degrees system with complex damping/speed relations.
